Just as I was feeling fatherly having made a hearty dinner of salmon with cous-cous I was cleaning up the large volume of cous-cous on the floor and table when the vacuum cleaner swallowed a napkin. This would be fine if it just sucked it into the bag but the napkin lodged somewhere in between and caused suction to be limited. So I tried disassembling the hose and discovered that it is hard to get to the place where things lodge, probably in order to sell wing-nuts like me a new vacuum whenever this happens. I did manage to find this helpful chart so my next step is to try to troubleshoot the derned thing.
